The displacement of the movable wall or counter plate, and furthermorethe movement oi the 35 press plates and the sheets of cellulose from thecontainer, can be effected by the head or pressure member that isconnected to the pressing plunger and moved by the latter. This head orpressure member is moved during the operation of 0 pressing in theforward direction, is then arrested, and then returned into its initialposition.

It may, however, also be forwarded stepwise in the event that thecellulose sheets require to be-` plates. The sheets thus fall outautomatically in succession, and can then be conveyed in any directionby means of suitable conveyor members arranged below the container. Inthis connection a conveyor belt may be provided upon which the sheetsare suitably distributed and fed to the site of any further treatment.

According to the invention the said inclined discharge track isautomatically formed upon lo the said plate is equipped with inwardlydirected inclined slide-ways, upon which, during the inward movement ofthe plate,

the end of the inclined track moves upwardly. w

plates travel in the interior of the container.

It is of particular importance, in order to se- These arms arepreferably connected to a rotatable middle member in such a manne-r that1n accordance .with the direction of rotation of the middle member thearms lock the end or counter plate on the container or unlock it topermit withdrawal. The bolts or locking arms serve to secure thepressurey for maintaining a tight joint by wedge action in their outwardmovement.

The movement of the wall can be eiected by any operating agent. In orderto secure very simple conditions the movement may be produced by thehead or pressure member which may conveniently serve for moving the wallin both directions. It is furthermore important for operating the pressto set the press plates, after the treated sheets of cellulose have beendischarged, in a manner to permit immediate reception of a new charge.For this purpose thin press plates are arranged in groups, and separaedby thicker press plates, the latter intervening between the said groupsof thin plates. The press plates of greater thickness are moved by themovable head or pressure member with the aid of a exible tractivemember, preferably in the form of a sprocket chain, in such manner thatthey follow the head or pressure member, the tractive member at the sametime serving to maintain the thicker plates suitably spaced apart, andat a, required distance from the head or pressure 55 means whereby theend or counter plate or member. Within the groups. themselves there arefurther provided spacing members in the form of links acting likewise inthe manner of a chain, but of a form to prevent entanglement.

`It is further essential, in order properly to operate the press, vtodispose as quickly as possible of the lye pressed out from the plates.For this purpose each press plate may be composed, according to theinvention, of three layers united together the outer layers consistingof solid perforated plates, and the inner layer of metal network, thesaid middle layer thus permitting convenient lateral discharge of theexpressed lye through the passages formed therein.

view of the abutment is coupled with the head or pressure member.

Figure 8 is a. plan view Figure 7 is a longitudinal exteriorcorresponding to Figiure'l.'

Figures 9 to 12 are detail views of parts of the device illustrated inFigures '1 and 8, Figure l2 being a section along the line I2-I2 ofFigure '1.

The press is provided with a container 3 having a perforated falsebottom 4 and xedly supported by means of feet on a plurality ofbase-members or pedestals I, of which only the one at charge end of thepress is illustrated. At the discharge end the supporting feet areformed on a frame 2 which is of a U-shape. The press-plates togetherwith the cellulose sheets placed between them in known manner arearranged in the container bottom 4 so that they may be moved in thehorizontal direction. According to the invention the press plates 5 arearranged in groups, each comprising six plates, and between the groupsthere are interposed thicker plates 6. The'plates are positioned betweena movable head or pressure member 1 and the end plate or abutment 8forming the movable wall at the discharge end of the container 3, thesaid end plate or abutment being in the present case pressed tightlyagainst the frame 2.

The head or pressure member 1 is moved in the usual way on the one handby the plunger 9 against the end plate orabutment 8 and on the otherhand away from the latter by means of the tension rod I operated by aretracting cylinder not illustrated.

The end plate or abutment 8 is provided with two crabs I I disposed oneat each side and mounted to travel on rails I2 which are connectedtogether at the outer ends by a transverse member I3 and supported uponpillars I4 to form a track on which the end plate or abutment 8 can thusmove in the horizontal direction.

Adjacent the base member I means are prosheets discharged from thecontainer transmitting rotation to the the ds 1 are drawn out of of Vanopen rectangular form or above the vided for the reception of thecellulose sheets, such as a carrier I which may be moved in a transversedirection and into vwhich the cellulose 3 may.' fall. In order to ensurea suitable falling path a sheet metal chute I6 is secured to the foot 2.

The end plate or abutment 8 is detachably secured `to the container 3 orthe frame 2 thereof by means of a locking mechanism. For this 4purpose arotatable disc I1 is mounted on the outside of the end plate or abutment8, and four arms I8 are pivotally connected to the disc I1, each of thesaid arms terminating in prongs I9. In the locking position as shown inFigures 1-4, these prongs I9 are received, in the case of each arm I8,in the space formed between the end plate or abutment 8 on the one handand a nut 2l on the other hand, which nut is screwed on to the outer endof 'a longitudinally disposed spindle 20, having the end portion formedas a screw bolt. As may be seen especially from Figure 4 the parts ofthe end plate or abutment 8 destined to be engaged by the forked prongsI9 of thearms I8 are provided with inclined or wedge surfaces so that onthe outward movement of the prongs I9, which also have inclined surfacesin contact with the inclined surfaces ofthe end plate or abutment 8, anincreasing pressure is exerted on to the end plate 8 with the resultthat the packing 22 in the inner face of the end plate 8 is accordinglypressed rmly against the frame 2. Adjustment of the pressure applied tothis packing may be effected by adjustment of the nut 2I.

Fixedly mounted on the rotatable disc I1 is a toothed segment 23engaging with a worm 2 mounted on a spindle 28 carried by bearings 28and 21 secured to the end plate or abutment 8; the spindle 28 may berotated by means of a hand-wheel 25 in one or the other direction, thusy and thereby to the disc I1 to engage or disengage the forked prongs I9on each ofthe arms I8 in relation to the aforesaid spaces. 1f the armsI8 engagement to the extent to the end plate or abutment 8 may be movedin the outward direction from the frame 2 by means of the crabs II, asthe end plate or abutment 8 is provided with bores 29 of a sizepermitting the outward movement over the nuts 2|.

Fixed to the inner side of the end plate 8 are two iiat brackets 30(Figures 5 and 6) each of the said brackets being provided with anobliquely directed guide-slot 3|. Each guide-slot is engaged by a rail32 in such a manner that the outwardly directed end of the rail may movealong the slot 3i in either direction. The other end of each rail 32 ispivoted to a rail 33 slidable horizontally on the adjacent side-wall ofthe container 3, the rail 33 moving on a guide rail 34 secured to thewall of the container.

Underneath the oblique guide slot 3l there is pivotally connected toeach lbracket 30 a rod 35 which is likewise mounted slidably upon theside wall of the container 3 in guides at 36 and 31. A shallow recess 38-is formed in the upper edge of the rod and serves, in 'the outwardmovement of the rod, to engage with one arm of a double-armed pawl 40pivotally connected to the guide-rail 34, when the rod 35 reaches theposition shown in Figure 6. The other arm of the pawl is of the form ofa locking nose 4I which in. the position shown in Figure 6 may engagewith a corresponding recess in the rail 33 to maintain the latter in xedposition.
